MARTIN .TEWELL, OF CLINTON, MAINE.

MOWING-MACHINE.

Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed October 5, 1905- Serial No. 281.419-

To all whom 'it may concern:

Be it known that I, MARTIN JEwELL, a citizen of the United States of America, and a resident of Clinton, in the county of Kennebec and State of Maine, have invented certain new and useful Improvements in Mowing-Machines, of which thefollowing is a specification.

This invention relatesto mowing machines and has for its -object-the production of a machine which will facilitate the labor imposed during the cutting of grass or grain by reducing to a minimum the friction between the several elements, this desired result being attained by dispensing with gearwheels and employing comparatively few parts to effect the various operations of the machine.

It has for a further objecttthe production of a machine in which the finger bar may be automatically lifted when the machine is backed or may be lifted by theoperator through the medium of either a foot, lever or a hand lever,as desired.

Another object in view is the production, of-a machine in which gear wheels or their equivalents are entirely dispensed with and the reciprocation of the knife is derived entirely from a revoluble zigzag wheel, so constructed as to avoid dead centers.

The invention consists in several features of construction and combination of elements which will be. thoroughly understood by the description and claims to be hereinafter. given.

Of the drawings: Figure 1 represents a plan of a mowing-machine embodying the features of this invention, the extreme end of the finger bar being broken, away. Fig. 2 represents a side elevation ofthe same. Fig. 3 represents a front elevation of the same with the tongue or pole out in section. Fig. 4

represents a sectional elevation of the casing inclosing the actuating wheel and showing in elevation the swinging members actuated by said wheel and from which a reciprocatory movement is imparted to the cutter bar, the cutting plane being on line 4-4: on Fig. 5,. Fig. 5 represents a sectional plan of a portion of the main frame showing the actuating wheel, the clutch for operating the same and the elements operated by said actuating wheel to transmit reciprocatory movement to the cutter bar. Fig. '6 re resents a sectional elevation of the same, t e cutting plane on line 66 on Fig. 5. Fig. 7 represents a side elevation of the devices for lifting the finger-bar. Fig. 8 represents a sectional elevation of a portion of the main frame showing its attachment to the tongue or pole and the means for supporting axle bearings, the cutting plane being on line 88 on Fig. 5. Fig. 9 represents a section of one of the bearings of the main axle. Figs. 10 and 11 represent, respectively a sectional plan and a sectional elevation of the connection between the actuating lever and the pitman for reciprocating the knife blade. Fig. 12 represents a sectional elevation of the main shoe for the finger bar. Fig. 13 represents a sectional elevation of the cutter bar looking toward the main shoe, the cutting plane being online 1313 on Fig. 14. Fig. 14 represents a sectional plan of the portion of the cutter bar and the main shoe showing the knife blades at one extreme of their movement. 7 Fig. 15 represents a similar section with the front guard blade removed and showing the cutting blade at the opposite extreme of its movement. 'Fig. 16 represents an elevation of one of the actuating pawls. Fig. 17 represents an elevation of the inner side of the finger bar lifting drum. Figs. 18 and 19 represent, respectively, an elevationand section of the link for o erating the clutch'pawl actuating lever. li ig. 20 represents a rear elevation of the cap for the trunnions of the clutch pawl actuatingI lever,

and Fig. 21 represents a diagram owing the operation of the waved rim on its rollers at the turning points to prevent dead centering.

Similar characters designate like arts throughout the several figures of the rawlngs.

In the drawings, 10 represents a main axle or shaft of this improved mowing machine,

. the ends of said shaft having secured thereon the'supporting wheels 11 of usual construction. The axle 10 is supported in two bearings 12, each of which is provided with a plurality of roller members 13 for the purpose of reducing to a minimum the friction upon said axle in its revolution 1n said bearlngs 12. The

rolls 13 are mounted in a, cage 14 of any suitable construction. The ends of the bearings 12 are provided with recesses having shoulders against which rests a washer 15 between which and a washer-16 bearing against the hub of the wheel 11 are interposed a series of balls or other anti-friction elements 17 to prevent any thrust of the wheels or other dev ces turning with the axle 10 from acting upon the roller cage 14. One portion of the bear- 7 bolt 23, the free end-of which has threaded thereto a nut 24. The shank of said eyebolt 23 is adapted to enter a slot 25 in the free end of the cap 20. By means of this device the bearings 12 may be securely clamped to the main frame 19 and owing to the conformation of the enlargement 18 they will readilyaline themselves with the main axle 10. The main frame 19 is secured to the poll or tongue 26 by means of bolts 27 assing through slots 28in the ears 29 of said ame 19. This provides for a ready means for adjusting the angle of said pole or ton ue 26 to the main frame to adapt it to different heights of horses.

Secured to the main axle 10 by a pin 30 is a clutch wheel 31 provided with a plurality of inwardly projecting teeth 32. Loosely mounted upon the shaft 10 adjacent to the hub of the clutch wheel 31 is a sleeve 33 upon which is securely mounted the actuator wheel 34 rovided with a continuous zigzag rim 35.

he sleeve 33 also has mounted thereon a member 36 rovided with a groove 37 which is engaged y anti-friction rollers 38 in the endof a forked lever 39 pivoted .to the frame The hub of the member 36 is provided with a projection 41 which engages with a similar projection 42 on the hub of the actuating wheel 34, the whole being constructed to provide for the revolution together of the wheel 34 and the member 36, while at the same time said member 36 is free to be moved toward and from said wheel 34. This member 36 is provided with ears 36 to which are-articulated links 43, the opposite ends of which are articulated to levers 44 pivoted at 45 in chambers 46 in the wheel 34. The chamber 46 is provided with walls to limit the movement of said levers 44 in either direction. The free end of the lever 44 engages with a awl 47 pivoted at 48 to the wheel 34 and he (1 in engagement with the teeth 32 by means of a spring 49. The wheel 34 is provided with a p urality of pawls 37 and these pawls are so arranged relative to the teeth 32 that when one pawl is in full engagement with said teeth other pawls are in partial engagement therewith, this arrangement being for the pur ose of insuring an engagement with the teet 32 for a shorter distance than the width of a tooth, as it is very desirable in the operation of any. mowing machine to start the operation of the cutter bar as soon as the mowing machine' is moved forward. This clutch mechanism accomplishes this object and causes the reciprocation of the knife as soon as the wheels 11 are moved forward.

' or strut 69 in the opposite direction.

The trunions 45 of the pawl-operating lever 44 are tapered and are provided with bearings in the wheel 34 and the caps 50 (see Fig. 20) secured thereto. The ends of the awloperating levers 44 articulated to the lin s 43 are also rovided with tapered trunnions, each of which has a bearing in a link 43, said links 43 being secured together by means of a bolt '51 one end of which is headed and provided on its other end with a nut 52 threaded thereto, said nut being provided with a toothed flange which is engaged by means of a s ring pawl 53 to prevent said nut from unloc ing, (see Figs. 18 and 19). The zigzag wheel or waved wheel 34 is inclosed by a casing formed in two parts, 54-55, pivoted together at 56. This casing surrounds the clutch mechanism and the upper portion 55 of the casing is held normally in a closed 0- sition by means of the hook or any suita 1e fastening device 57 engaging with the eye 58 forming a part of the cap 59 bolted to the main frame 19.

The upper portion 55 of the actuating wheel casing is provided at its front end with lateral hollow extensions 60 in which is inclosed the elements which assist in changin the revoluble motion of the actuating whee 34 into a reciprocatory movement to actuate the knife bar. This movement is effected as follows: On either side of the casing 54 and immediately beneath the lateral extensions 60 are two substantially parallel members 61 forming a part of the main frame 19. These members 61 are each rovided with two ears 62 projectin upwar j into the lateral ex tension 60 o the whee casing. Upon a pin 63 interposed between said ears are mounted links 64 se arated by a sleeve 65. The lower end of sai links have articulated therewith the swinging member 66 which is provided with upwardly projecting cars 67, each pair of which are connected by a pin 68 ada ted to limit the movement in one direction 0 the struts or arms 69 pivoted at 76 to the links 64. Upwardly projecting lugs 71 from the member 66 limit the movement of the arm Each of the arms or struts 69 has ivoted at its free end rollers or other suitab e bearing surfaces 72 which are adapted to engage with the walls of zigzag or wavedrim 35 which will form radial shoulders adapted to cooperate with said struts 69 toswing the dewoe to which they are ivoted about the pivots 63. It is obvious t at a revolution of the wheel 34 will cause the zigzag or waved rim 35 to act upon the rollers 72 in the ends of the struts 69 to swing the links 64 about their pivots 65 and thereby cause a reciprocatory movement of the member 66;

The turning point of the inner face of the rim 35 is made of a eculiar construction, the curve on either si eof the center being of a different diameter, as shown in Fig. 21, 130

with

avage-us in which the rim ismoving in the direction ofthe arrow (1, and as the roll 72 moves-down the inclined face 6 its movement in 'the di-' on the-curve d of thegrea'test diameter. As soon as the roll-reaches the center itengagesthe curve e of the smaller diameter and quickly regains an'inclined face f thereby securing a constant movement of the swinging member 66. This peculiar construction of the'turning points obviates to some degree the noise which usually occurred when the roll 72 reached the turning oint beforethis construction was provided and causes a smootherand more effectiveoperation of the knives, or cutting devices. This'operation prevents any dead centering ism and insures-a continuous'swinging'movement of the'member 66 as'long as the actuating wheel 34 continues to revolve. The member 66 is provided with hooks 73 on which are mounted members 74 which by means of a frame 19 an the plate 59. The opposite end of the lever 76 is rovided with'a revoluble sleeve 78 pro-vicihd with 'trunnions 79 having bearings'in the arms 80 of the it man 81 the opposite end of'which'is'provi ed arms 82, the ends ofwhich are=provided with sockets to engage a ball-8'3 secured to the-knife 84 of the nger bar 85. The finger bar 85 is provided with the usual'fingers or guards 86. The movement of the pitman'81 is such as to cause a sufficientreci rocation of the knives84 to cause each knife section to pass through two guards 86, thus doubling tion it may make.

port for the finger the efficiency of the knife in each-reciprocaprovidesa'suitable supbar and has secured thereto upwardly projecting ears 88to which by means of pins 89-is connected a drag bar 90 ivoted at 91 to a member 92'freely revolu le in a bearing 93 in the end of one of the members 61 of the main frame 19. In lifting the finger bar to ass obstacles the dragbar is moved about t e pivot 91 and to adjust the finger bar for various cuttings the drag bar is moved about the axis of the shank 94in an obvious manner.

seat 95 is rovided for the operator-suitably supporte by wardly to the rear-from the main frame 19 and on either side of this arm foot-rests 97 Theinner shoe 87 are provided. To the right and front of the 1 seat 95 is a foot pad 98 on theend of-the bent rod 99 secured to one arm of a bell crank mounted upon 'a-stud or shaft 101. .The other arm of said lever 100 is provided with-an eye 102 between which and an adjustable hook 103 on the tongue or pole 26 is interposed a counterbalance spring 104. On the stud or shaft 101 is loosely mounted a drum 105to which-at 106 vided with nuts on either side of her by adjusting of the mechan-- pin 75 are pivoted together-and, to a lever 76 ivoted at 77 betweenthe main ing the'handle '1-16 and -him *willcause the drum about its'sup orting stud or shaft 101'there- 'ing knives are not in operation.

an arm 96 extending up is secured acha'in 107 which passes under a pulley 108 secured in a bifurcated member 109' mounted upon a stay rod 110, provided with an eye 111 through which a pin 89 The threaded ends-of-said rod are .pro-

said memwhich the cutter bar may be-ahned.

' The drum 105-is provided on its periphery with-a plurality of teeth 113 with which engages a bolt or other fastening device 1144 mounted inbearings 1150n a-hand lever 116 loosely mounted upon the shaft 101. A

spring '11? operates u on-said bolt or fastening device to norma ly cause it to engag with said'teeth 113 pivoted at'119 operates through-the medium while a hand grip 118 of a connecting rod 120 to withdraw said bolt-from-engagement with said teeth 113'as desired.

It is obvious that the operator by grasppulling it towards '105 to be -moved by carrying t erewith the chain 107 the'opposite end of which is secured to the lifting arm 121 secured to the inner-shoe-87 This operation of the handle 116 Will wrap the am 107 around the drum 105 and cause the'inner-shoe 87 with the finger'bar 85 to'be lifted, and whenthe shoe 87 has been lifted to its greatest height a further movement of the chain will cause the finger bar to be tilted-around 'the axle of the pms 89 having bearings in the bifurcated end 122 of the drag bar 90. If a sufiicient inclination of the er bar is not secured 'b the first movement of the handle 116 the operator may push the same forward and secure a second purchase upon the ratchet 113 andb a sec- ;ond-movement to the rear a further li t of the cutter bar will be secured. This operation may 'sary to lift the finger be'repeated as many timesas is necesbar to any'desired inpoint of a practically often desired in movfromone point to the other when the clmation, even to the vertical posltion as is A weighted stop pawl 123 pivoted at 124 prevents anyreturn movement of the drum 105. The'drum 105 has-a laterally projecting'lug 125 with which the bell-crank lever 00 engages when the operator places his foot'upon thefootpad 98'to cause the drum 105 to be rotated aboutits axisto cause a lifting of the shoe 87 andthefingerbar 85, the spring 104 assisting in this operation. Theopposite side of the drum is provided with a laterally projecting shoulder or lug 125* whichis engaged by an-arm*1-26 mounted -up0n'=the stud or shaft 101 the outer end of said'arm wbeing articulated toa connecting rod 127 the other end of which is articulated to the end of a lever 128 pivoted at 29* to the front end of the tongue or pole.

The upper end of the lever 128 has secured thereto the whifiietree support 30* carrying the whifiletrees 130* to which, when in operation, the horses are secured. It is obvious that any backing of the horses will pull upon these whiflletrees in such a manner as to move the lever 128 about its pivot and cause the rod 127 to move the arm 126 about its pivot thereby through the medium of the lug or shoulder 125* moving the drum 105 to cause a wrapping thereon of the chain 107 and as a result secure the lifting of the shoe 87 and the finger bar 85. By this construction a lifting of the finger bar-1s effected by either a hand lever, foot-operated lever, or through mechanism operated been completed the finger bar may be by the backing of the horses. The mechanism which causes the lifting of the finger bar by the backing lift the shoe87 and the finger bar 85a suflicient distance ,to disengage it from the ground to prevent accident while moving the machine to the rear. The foot lever is arranged so as to lift the finger bar so that it will pass ordinary stumps or other high obstacles are in the path of the finger bar and when is desired to return to the barn after the mowing has ifted to an extreme height and even into a vertical position by means of the hand lever 116.

To the rear of the hand lever 116 is another lever 129 pivoted at 130, the lower end of which has connected therewith a rod 131 the opposite end of which is secured to a lug 132 on the'drag bar head 122. The lever 129 is rovided with a spring-operated lock-- ing be t 133 which engages with detent notches 134 in a quadrant 135. "A movement of the lever 129 in either direction about its fulcrum 130 will tilt the drag bar 122 and 90' about the axis of the shank 94 thereof in the bearing 93. The tilting of the drag bar causes a similar tilting of'the finger bar 85 to secure a variation in the height of the cutting above .the surface of the ground.

Somewhat in advance of the inner shoe 87 is a bifurcated lever 136 pivoted to the pole front of the seat 95 the main frame is provided with a tool box 140, said frame being also provided at 141 with a recess for the oil can.v The inner shoe is provided with a which is articulated to a lever 145 of the horses is provided to obstacles but whensup lemental late 142'secured to the under su ace thereo to prevent undue wear. The shoe 87 is also provided with a bent arm or guard 143 to force the material cut out of the way of the o erating parts of the machine.

The clutc actuating lever39 has articulated thereto a rod 144 the opposite end of ivoted at 146 to the frame 19. The opposlte end of said lever 145 bears against a cam 147.0n the inner face of the drum 105 the lever being held normally in engagement therewith by a spring 148. The cam 147 is so constructed and positioned that as soon as thedrum 105 is movedto lift the shoe 87 it will immediately act upon the levers 147 to disconnect the clutch mechanism and thereby prevent further reciprocation of the knives 84. It is believed that the operation of this invention will be readily understood without further description.
